Problems solved by technology

The anti-removal part engages with the flow path forming part in an assembled state, but the way of applying external force accompanying nozzle insertion is unpredictable, so the external force applied to the anti-removal part may act and loosen the engagement with the flow path forming part

Embodiment Construction

[0085] figure 1 It is an explanatory diagram showing the outline of a fuel supply device FS that guides fuel supplied from a fuel supply nozzle FN to a fuel tank FT of a vehicle. The fuel supply device FS of this embodiment includes: a nozzle 10 as a flow path forming member; a fuel vapor port 16; a filler pipe FP; a check valve TV; a fuel vapor pipe NT; a gas release valve BV; The nozzle 10 is fixed to the fuel supply chamber FR of the vehicle by the attachment member FE, and receives the insertion of the fuel supply nozzle FN into the fuel supply port FC which is an insertion port. The nozzle 10 is connected through a fuel tank FT, a filler pipe FP, and a fuel vapor pipe NT. The filler pipe FP is, for example, a resin pipe having a corrugated structure at two places, and can expand, contract and bend within a certain range. The filler pipe FP is connected to the fuel tank FT via a check valve TV. Fuel ejected from the fuel supply nozzle FN inserted into the fuel supply po...

Abstract

A flow path-forming member mounted to a pipe opening end of a filler pipe forms an insertion flow path portion in which a fueling nozzle is inserted, such that the insertion flow path portion communicates with a fuel flow path. An opening end engagement portion is arranged to cover a flow path inner circumferential wall a flow path outer circumferential wall and a peripheral wall of the fuel flowpath at the pipe opening end around the fuel flow path and is engaged with the filler pipe at the pipe opening end. The flow path-forming member mounted to and engaged with the filler pipe is fastenedto the filler pipe by means of a fastening structure, in the state that a pipe outer circumferential wall of the filler pipe is covered by an outer circumference covering portion that is provided from the opening end engagement portion to a downstream side of the fuel flow path. This configuration enhances the effectiveness of preventing the flow path-forming member that forms the insertion flowpath portion for the fueling nozzle from being unintentionally detached.

Description

[0001] Cross-reference of related applications [0002] This application claims priority from Japanese application P2016-192637A filed on September 30, 2016, the contents of which are incorporated herein by reference. technical field [0003] The invention relates to an oil supply device. Background technique [0004] The fuel supply device includes a flow path forming member forming a nozzle insertion passage for inserting the fuel supply nozzle, and the flow path forming member includes a fuel supply opening and closing valve such as a flapper valve. Since the flow path forming member needs to be replaced due to the breakage of the valve, a structure in which the flow path forming member is detachable as shown in JP 2015-67139 A has been proposed. In this oil supply device, a disengagement-preventing member is assembled to the flow-path forming member, and the assembled disengagement-preventing member enables the flow-path-forming member to be engaged with an attachment o...
